Is the typical security portfolio of system administrators wide enough to form the foundations of an effective information security program? Not really. In fact its some way short. Security Analysts need to have a grasp not only on file system permissions, they need to know how attackers actually elevate privileges...

Successful exploitation of this vulnerability could allow escalation of privileges to full administrative access. The privilege escalation could provide the attacker a vector for making changes to settings, or initiating a complete device shutdown causing a denial of service...

So, what is this new vulnerability all about? It’s a privilege escalation vulnerability that gives an attacker SYSDBA privileges. In order to perform the exploit, one needs to have CREATE TABLE and CREATE PROCEDURE privileges as well as EXECUTE privileges on DBMS_STATS package...

Siemens has reported a privilege escalation vulnerability in the Siemens COMOS database application. Authenticated users with read privileges could escalate their privileges by exploiting this vulnerability. Thus, the attacker is able to gain administrator access to the database...

Explaining what goes through an attackers head when they get a shell is virtually impossible, even more so to generalize into a methodology, but I’ve tried to do that with the "Three P’s of Post Exploitation” - they are in a certain order for a reason, but certainly up to circumstance to what order is best...

Researchers identified an authentication bypass vulnerability leading to privilege escalation in the ICONICS GENESIS32 and BizViz applications whcih can allow an attacker to bypass normal authentication methods, granting full administrative control over the system...

Apple has released critical security updates for OS X and Safari to address several vulnerabilities which could allow an attacker to obtain sensitive information, execute arbitrary code, escalate privileges, conduct a cross-site scripting attack, or cause a denial-of-service...

Researchers have identified a buffer overflow vulnerability in multiple components of the ABB WebWare Server application which could lead to a denial-of-service for the application and privilege escalation or could allow an attacker to execute arbitrary code...

Researchers have identified multiple vulnerabilities in the Invensys Wonderware Information Server which if exploited could allow denial of service, information disclosure, remote code execution, or session credential high jacking. Invensys has developed a security update...

Least privilege is the notion that in a particular abstraction layer of a computing environment every module - such as a process, a user or a program depending on the subject - must be able to access only the information that is necessary for its legitimate purpose...

Most attacks are perpetrated inside the perimeter, so protection from an inside attack is important. Once an attacker is on the inside, it is easy to use SQL injection or other techniques to obtain data. Organizations are just beginning to understand the insider threat...

A buffer overflow vulnerability in the Robot Communication Runtime software used to communicate with IRC5, IRC5C, and IRCP robot controllers could allow an attacker to cause a denial of service and potentially execute remote code with administrator privileges...

Cisco has released six security advisories this week to address vulnerabilities that may allow an attacker to execute arbitrary code, cause a denial-of-service condition, operate with escalated privileges and bypass security restrictions...

Successful exploitation of these vulnerabilities could allow an attacker to log on to a vulnerable system as a user or administrator with the ability to execute arbitrary code or obtain full access to files on the system. Publicly available exploits are known...

Researcher Kuang-Chun Hung of ICST has identified an unsafe search path vulnerability. Successful exploitation may allow an attacker using social engineering to execute arbitrary code and gain the same privileges as the user that is currently logged into the system...

How do our organizations treat administrators (more specifically highly privileged users) when they are removed from active duty? It seems that in large organizations the issue is easier to at last draw a line around than in smaller orgs - but the problems remain...
